"abstract": "<p>Especially in Germany in the future road construction will be shaped less by the new construction but rather through<br>\nthe maintenance and renewal. Because the existing road substance is used up in growing ever stronger and quicker<br>\nmeasure. With reference to the steadily rising traffic load and for a qualified maintenance planning the knowledge of<br>\nthe real structural condition of an asphalt pavement gets more and more important. The present paper presents an<br>\napproach that forecasts the remaining service life of an asphalt pavement on the basis of asphalt parameters<br>\ndetermined by laboratory tests. Therefore asphalt samples were taken from existing asphalt pavements which are<br>\nalready bearing many years of traffic load and their specific asphalt properties such as stiffness and fatigue<br>\nresistance were determined by tests. The asphalt material properties of an asphalt road for several cross-sections (all<br>\nrequired cores about a length of 10m) and several sections (required cores with a distance between 100m and 150m<br>\nto each other) are determined and evaluated. Likewise, the volumetric properties of the asphalts and the material<br>\nproperties from the individual components in the asphalt mix are considered in the analysis and evaluation. With<br>\nthese results of the asphalt studies in the laboratory together with a forecasting method based on the analytical<br>\ndesign of asphalt pavements the possibility exists to give statements to the expected remaining service life of asphalt<br>\npavements.</p>",
